9 Everyone is permitted to copy and distribute verbatim copies
10 of this license document, but changing it is not allowed.
13 This version of the GNU Lesser General Public License incorporates
14 the terms and conditions of version 3 of the GNU General Public
15 License, supplemented by the additional permissions listed below.
17 0. Additional Definitions.
19 As used herein, "this License" refers to version 3 of the GNU Lesser
20 General Public License, and the "GNU GPL" refers to version 3 of the GNU
21 General Public License.
23 "The Library" refers to a covered work governed by this License,
24 other than an Application or a Combined Work as defined below.
26 An "Application" is any work that makes use of an interface provided
27 by the Library, but which is not otherwise based on the Library.
28 Defining a subclass of a class defined by the Library is deemed a mode
29 of using an interface provided by the Library.
31 A "Combined Work" is a work produced by combining or linking an
32 Application with the Library. The particular version of the Library
33 with which the Combined Work was made is also called the "Linked
36 The "Minimal Corresponding Source" for a Combined Work means the
37 Corresponding Source for the Combined Work, excluding any source code
38 for portions of the Combined Work that, considered in isolation, are
39 based on the Application, and not on the Linked Version.
41 The "Corresponding Application Code" for a Combined Work means the
42 object code and/or source code for the Application, including any data
43 and utility programs needed for reproducing the Combined Work from the
44 Application, but excluding the System Libraries of the Combined Work.
46 1. Exception to Section 3 of the GNU GPL.
48 You may convey a covered work under sections 3 and 4 of this License
49 without being bound by section 3 of the GNU GPL.
51 2. Conveying Modified Versions.
53 If you modify a copy of the Library, and, in your modifications, a
54 facility refers to a function or data to be supplied by an Application
55 that uses the facility (other than as an argument passed when the
56 facility is invoked), then you may convey a copy of the modified
59 a) under this License, provided that you make a good faith effort to
60 ensure that, in the event an Application does not supply the
61 function or data, the facility still operates, and performs
62 whatever part of its purpose remains meaningful, or
64 b) under the GNU GPL, with none of the additional permissions of
65 this License applicable to that copy.
67 3. Object Code Incorporating Material from Library Header Files.
69 The object code form of an Application may incorporate material from
70 a header file that is part of the Library. You may convey such object
71 code under terms of your choice, provided that, if the incorporated
72 material is not limited to numerical parameters, data structure
73 layouts and accessors, or small macros, inline functions and templates
74 (ten or fewer lines in length), you do both of the following:
76 a) Give prominent notice with each copy of the object code that the
77 Library is used in it and that the Library and its use are
78 covered by this License.
80 b) Accompany the object code with a copy of the GNU GPL and this license
85 You may convey a Combined Work under terms of your choice that,
86 taken together, effectively do not restrict modification of the
87 portions of the Library contained in the Combined Work and reverse
88 engineering for debugging such modifications, if you also do each of
91 a) Give prominent notice with each copy of the Combined Work that
92 the Library is used in it and that the Library and its use are
93 covered by this License.
95 b) Accompany the Combined Work with a copy of the GNU GPL and this license
98 c) For a Combined Work that displays copyright notices during
99 execution, include the copyright notice for the Library among
100 these notices, as well as a reference directing the user to the
101 copies of the GNU GPL and this license document.
103 d) Do one of the following:
105 0) Convey the Minimal Corresponding Source under the terms of this
106 License, and the Corresponding Application Code in a form
107 suitable for, and under terms that permit, the user to
108 recombine or relink the Application with a modified version of
109 the Linked Version to produce a modified Combined Work, in the
110 manner specified by section 6 of the GNU GPL for conveying
111 Corresponding Source.
113 1) Use a suitable shared library mechanism for linking with the
114 Library. A suitable mechanism is one that (a) uses at run time
115 a copy of the Library already present on the user's computer
116 system, and (b) will operate properly with a modified version
117 of the Library that is interface-compatible with the Linked
120 e) Provide Installation Information, but only if you would otherwise
121 be required to provide such information under section 6 of the
122 GNU GPL, and only to the extent that such information is
123 necessary to install and execute a modified version of the
124 Combined Work produced by recombining or relinking the
125 Application with a modified version of the Linked Version. (If
126 you use option 4d0, the Installation Information must accompany
127 the Minimal Corresponding Source and Corresponding Application
128 Code. If you use option 4d1, you must provide the Installation
129 Information in the manner specified by section 6 of the GNU GPL
130 for conveying Corresponding Source.)
132 5. Combined Libraries.
134 You may place library facilities that are a work based on the
135 Library side by side in a single library together with other library
136 facilities that are not Applications and are not covered by this
137 License, and convey such a combined library under terms of your
138 choice, if you do both of the following:
140 a) Accompany the combined library with a copy of the same work based
141 on the Library, uncombined with any other library facilities,
142 conveyed under the terms of this License.
144 b) Give prominent notice with the combined library that part of it
145 is a work based on the Library, and explaining where to find the
146 accompanying uncombined form of the same work.
148 6. Revised Versions of the GNU Lesser General Public License.
150 The Free Software Foundation may publish revised and/or new versions
151 of the GNU Lesser General Public License from time to time. Such new
152 versions will be similar in spirit to the present version, but may
153 differ in detail to address new problems or concerns.
155 Each version is given a distinguishing version number. If the
156 Library as you received it specifies that a certain numbered version
157 of the GNU Lesser General Public License "or any later version"
158 applies to it, you have the option of following the terms and
159 conditions either of that published version or of any later version
160 published by the Free Software Foundation. If the Library as you
161 received it does not specify a version number of the GNU Lesser
162 General Public License, you may choose any version of the GNU Lesser
163 General Public License ever published by the Free Software Foundation.
165 If the Library as you received it specifies that a proxy can decide
166 whether future versions of the GNU Lesser General Public License shall
167 apply, that proxy's public statement of acceptance of any version is
168 permanent authorization for you to choose that version for the
